Embodiment Construction

[0034]According to the present invention, granules made of biocompatible metal material, more particularly based on titanium and / or its alloys, are produced with characteristics such as to make the insertion of granules and osseointegration, once in place, simultaneously possible during the surgical phase.

[0035]The term “granules” is used in the present description to indicate solid particles having any geometry whatsoever, preferably, but not exclusively an approximately spherical geometry, and having average size of the order of a few millimetres, preferably less than 7 mm, even more preferably but not necessarily between 4 and 6 mm.

[0036]In the case in which these granules have a spherical geometry, they will be characterized by an outer diameter of a few millimetres, preferably less than 7 mm, more preferably but not necessarily between 4 and 6 mm.

[0037]According to a preferred embodiment of the present invention, said granules will have spherical shape, in particular they will ...

Abstract

More specifically, granules made of biocompatible metal material, preferably osteoinductive metal, for use in vertebroplasty surgery, as well as the use of these granules for this purpose, are the object of the present invention.

Description

FIELD OF THE INVENTION[0001]The present invention concerns transcutaneous vertebroplasty or kyphoplasty surgery.[0002]More specifically, granules made of biocompatible metal material, preferably osteoinductive metal, to be used in vertebroplasty, and also the use of these granules for this purpose, are the object of the present invention.BACKGROUND OF THE INVENTION[0003]Vertebroplasty, or kyphoplasty, is a treatment used in patients with vertebral compression fractures.[0004]Many causes can determine the collapse of a vertebra under the action of the compressive forces that normally affect the spinal column: painful compression fractures from osteoporotic, traumatic or osteolytic compression of the thoracic or lumbar vertebrae can occur. The main causes are osteoporosis, multiple myeloma, vertebral metastases, or more simply a trauma.[0005]As is known (see accompanying FIGS. 1 and 2), the vertebrae 10 have a main body 11 of a substantially cylindrical shape (or better, slightly “hou...
